MACHINE FOR CUTTING FABRICS.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed November 29, 1905. Serial No. 289,690.

Be it known that WILLIAM THOMAS GOLLEDGE and ROBERT HUMPI-IRYS HARRY, subjects of the King of the United Kingdom of Great Britain and Ireland, and residents of 53 Curtain road, London, England, have invented certain new and useful Improvements in Machines for Cutting Fabrics, of which the following is a specification.

This invention relates to an improved machine for cutting fabrics and is designed for use by clothiers and others.

The invention has for its object to provide a simple and effective machine driven by, power derived from any suitable source transmitted thereto by means of flexible shafting and so arranged and constructed as to permit of its ready manipulation by hand during the cutting operation.

In carrying the invention into effect we employ two shear blades one of which is preferably fixed while the other is reciprocated in the vertical plane. The blades aforesaid are carried by a suitable frame which may also form a case for the operating mechanism and which frame is provided with a handle for effecting the Inanipulation during the cutting operations. The Inovement of the reciprocating blade is effected by means of a cam, or other equivalent device, mounted upon a vshaft or spindle disposed with its center in the vertical plane. A suitable coupling or connection is provided upon the aforesaid shaft for the attachment of the flexible shafting. The movable blade is secured to a rod working in suitable guides and to which rod motion is imparted through a link or connecting rod operated by the cam or its equivalent as aforesaid. An adjustable guide or guard is provided to prevent the material impeding the action of the shears.

In order that the invention may be the better understood drawings are appended illustrating two forms of the invention in which:-

Figure l is a side elevational view partly in section of a machine constructed in accordance with the invention, Fig. 2 is a frontview of certain parts shown in section. Fig. 3 is a section on line A A Fig. l. Fig. 4 is a plan partly in section of the supporting foot of the machine. Fig. 5 isa front view of one ofthe guides for the reciprocating fork actuating the cutter. Fig. 6 is an elevational view to an enlarged scale of certain parts removed from the casing. Fig. 7 is a longitudinal sectional view of the parts shown in Fig. 6.

Referring to the accompanying drawings Figs. l to 5 a indicates a Cylindrical casing connected at al to a foot oz2 by means of the horizontal plate a3 through which passes a screw a4 tapped into the projection a5 the said projection being circular and provided upon its under side with a fiat surface for the attachment of the foot aforesaid. The projection a5 also serves as a means for the attachment of the handle a6 by which the manipueration. The case a at its lower end is provided with a stuffing box b and gland b1 through which passes the vertical rod bL to the upper end of which is secured the fork b3. The ends of the fork are provided with pins carrying rollers b5 engaging a cani surface formed upon the vertical walls b(i b7 upon disks b8 b the part b8 being provided with a boss c2 recessed into the undersurface of the disk bJ the parts being secured in rotative engagement by means of pins such as c3 and receiving motion from the spindle c to which the uppermost disk'is secured by means of a key or other suitable means. A distance piece c1 is also provided to insure the proper spacing of the edges of the walls b b7 which walls as aforesaid form the cam for effecting the vertical reciprocation of the knife their upper edges presenting an undulated outline as shown in Fig. 6. The distance piece c1 is recessed into the respective upper and lower faces of disks bs and bJ and prevents the lateral displacement of the fork b3 by limiting the inward movement of the rollers b5. The vertical displacement of the disk bS is prevented by lock nuts upon the lower end of the spindle c. Olainped between the upper surface of the casing a, which is suitably recessed to secure it, and the cap d closing the end of casing a is a disk c secured against rotation by means of pins such as c7 entering recesses formed in the casing. The cap d is provided with a central aperture through which passes a boss c4 formed upon the upper surface of the disk bJ which boss projects beyond tlie surface of disk cf and is provided with a screw thread engaging a thread formed in the disk c5, a washer being interposed between the upper surface of the disk and a shoulder formed upon the spindle c the lower portion of. which is of reduced diameter. Ball races are formed in the upperand lower surfaces of disk cG adapted to receive balls c cJ in order that the friction between tlie disks and the non rotative part cG may be as little as possible. The cap d is provided with a stuffing box and gland through which passes the spindle c.

the front of the said bosses being recessed or channeled as shown in Fig. 5.

f indicatesa cutter secured to the lower end of the rod b2, which is slotted for the purpose, by means of screw f1. The cutter is shaped as shown the back thereof working in a recess formed in the vertical portion of the foot a2.

The loot at its lower end terminates in a horizontal plate g slotted to receive the L shaped plates g1 sccured to the foot by means of screws g2, the underside of the plate being slotted to contain the horizontal members'of said plates. I

A. depending rod L forms a guard to protect the operators fingers and a spring h1 adjustably secured to the vertical member of the foot is provided to prevent the material rising during the cutting operation.

Motion is transmitted to the vertical spindle' by means ol' a flexible shaft, not shown and connected to the upper end ot said spindle in any suitable manner, Upon the rotation ol the shaft the cani surfaces acting upon the upper end ol the lork b3 cause the rod b2 to be rapidly reciprocated in the vertical plane and the machine being pushed forward by means of the handle the blade is brought into contact With the cloth or the like and the cutting effected. The edges of the plate g are suitably rounded or curved in order to facilitate the passage ol the machine through the cloth.

The action oi the machine Will be readily apparent from the foregoing description, the cutter being reciprocated in the vertical plane upon the rotation of the crank and the manipulation of the machine being effected by means of the handle.

What We claim is l. A machine for cutting.` fabrics, comprising a cylindrical casing having at one end a guide for a reciprocating, cutter bar and at the other a bearing for a rotative element designed to be connected to a iieXible shaft, a foot or support upon the casing, a presser foot for the material being cut, a knife guard, a handle for manipulating the device and a cam operated reciprocating` cutting' blade connected vto a forked rod the upper ends of which support rollers eng-aging the cam upon opposite sides of its periphery and guides for the said rod formed upon the inside of the main Casing.

2. 1n a machine for cutting fabrics,the combination with a driven shaft and a cam therein, of a forked rod carrying a cutting blade and the upper ends of which rod engage the driving cam upon opposite sides of its periphery and guides for said rod formed respectively at the lower end of the main casing and upon the interior thereof.

3. In a machine for cutting fabrics, the combination with a shaft to bc driven, a pair of disks spaced apart and mounted on the shaft, cam faces on the opposing faces of the disks whereby the disks form a cam-way, a rod provided with a fork at one end carrying means to engage the cam-way whereby the rod will be reciprocated upon the rotation of the shaft, a cutter at the free end of the rod and a foot with which said cutter coperates.

'4. In a machine for cutting fabrics, an outer casing comprisinga hollow body of circular cross section provided l at its lower end with a stuiing box and gland forming a guide for a reciprocating, rod carrying a cutting blade and at its upper end having a cap also provided with a stuffing box and gland serving as a bearing for a rotative element connected to a flexible shaft and plugs screwed into the wall of the casing at diametrically opposite positions such plugs having on their inner faces guide ways engaging the vertical members of a forked termination upon the reciprocating cutter i'od.

5. ln a machine for cutting fabrics, the combination with a rotative element driven by means of a flexible shafting, of a fixed disk rigidly secured within the main casing and having ball races' upon its upper and lower faces, a similar race being` formed upon the upper face of the driving cam and a second disk adjustably secured to an extension upon the said cam provided with a ball race upon its under surface and balls located in the said races and engaging the upper and lower faces of the fixed disk.
